This blog describes the use of Multi-cast delegate in UE4 and how to implement the Observer pattern using Multi-cast delgate. Delegate The role of delegate is to bind an object to its function, resulting in a function that can be called globally. This functionality has been built into C #, but it does not seem to be an official implementation in C + + 11. For the implementation of delegate in C + + 11, you

For the users of Photoshop software, talk about making a refreshing blue orange Fall Park character effect tutorial. Tutorial Sharing: 1, open the original material large map, create optional color adjustment layer, yellow, green, green adjustment, parameter settings such as Figure 1-3, the effect is shown in Figure 4. This step turns the yellow-green part of the background into orange-y

The background of the picture is mainly green, the change to orange Brown is simple, just turn the green to orange, and then turn the dark color to reddish-brown, and then add some light yellow to the high light section. Original Final effect 1, open the material picture, create an optional color adjustment layer, yellow, green adjustment, parameter settings such as Figure 1, 2,

As we all know, the relay is a small current to control the operation of a large current "automatic switch", in our lives, work everywhere. Now the "smart home" concept, there are many functional modules is actually "intelligent switch", remote switch, timing switch, condition trigger switch and so on.The Orange Pi one (arm Linux) control relay, described below, makes it easy to implement an "intelligent switch".Like

Cast (,) CAST, a data type conversion function in Oracle, explicitly converts a data type expression to another data type.

This article from: http://blog.csdn.net/xuejianwu/article/details/6931926X. Conversion operatorsConversion operators are used to implement the ability to convert the type of an input object into a sequence. The conversion method whose name starts with "as" changes the static type of the source collection but does not enumerate (lazy-load) this source collection. The method that begins with the name "to" enumerates the source collection and puts the items into the appropriate collection type.1. A

hand. If downcast and the type parameter is not polymorphic, dynamic_cast cannot be used and the compiler will give an error.dynamic_cast returns a null pointer if the type of the object is not the base class of the type that will be converted to. That is, a non-derived class object is converted to a base class object, or a base class object is converted to a derived class object, returning a null pointer.#include In this example, the base class object is converted to a derived class object and

Brief introduction JavaScript Object notation (JSON) is a text-based open standard designed for human-readable data interchange. JSON is derived from the JavaScript scripting language, which is used to represent simple data structures and associative arrays called objects. In the past, the vast majority of SaaS applications were used by enterprise customers. JSON is considered an efficient and efficient way to represent data on HTTP. Earlier, almost all SaaS applications that exposed WEB servic
